Sometimes you need a little time to search for a better solution. I changed the power supply. And now, we need only 5V voltage as input voltage, no 12V voltage are necessary.
It’s possible to operate the DC-to-DC step up converter with 5V voltage as input voltage too. ***smile***
This is the result … This is the result … with a provisional box.
Hi guys, I finished the tutorial about the clock!
9.1 The clock with 6x 7-segment display
Ok, now it’s finished: I present you “the clock”!
I control four 7-segment displays without any integrated circuit! The magic word is: multiplexing!
